We install the Tweet and Facebook "Like" buttons (plus Google+ and Pinterest) in your store regardless whether you have custom templates or not, or whether your store is based on the 2.0 or 3.0 template sets.

One of our most popular add-ons.
Let your customers post reviews or ratings of your store's products. Fully functional, self-maintaining (no need to receive the reviews and post them yourself to your store). Works seemlessly with any editor-based Yahoo! Store (requires php/mysql-enabled web hosting such as Yahoo! Merchant Solutions).
